At the end of modernism, the style of bravura painterly abstraction flowing out of the work of Willem de Kooning had come to seem egotistically melodramatic. And the abstractions of cool flat shapes and stripes flowing from Barnett Newman and Frank Stella seemed hollowly formal. The postmodernist stuff that followed seemed caught in a feedback loop of art about art, narrow formal games, and wink-wink pastiche.

But Capasso noticed Thaddeus Beal of Somerville: “Here’s this guy who’s making these paintings that are very complex, and based on fractal geometries and chaos theory.” It seemed like the beginning of something new in abstract painting. And over the past decade and a half it’s become a certifiable trend.

The DeCordova Museum’s grandly titled new “Big Bang! Abstract Painting for the 21st Century” rounds up 15 painters, mostly from New England, who reinvigorate abstraction by looking outside the narrow confines of art and drawing inspiration and imagery from computers, stars and constellations, quantum physics, data mapping, the Internet, genetics, squiggly microscopic critters. This is Information Age abstraction, thrilled by the wonders of all our fantastic new technology even as it notes that technology — computers, microscopes, telescopes, even animated cartoons — is ever coming between us and the natural world.

That’s not to say it’s scientific. “Sciency” might be a better word, because though this stuff evokes science, it’s mostly pretend. It’s fascinated with the “idea of data,” as one wall text smartly notes, but it imagines its own worlds rather than getting hung up on the real thing.

One dazzling example is Williamstown artist Barbara Takenaga’s paintings of what often look like radiating, spiraling galaxies. In Angel (2006), pulsing orbs stream inward, the currents seeming to fold and kiss in the center. These paintings are mesmerizing, like ’60s psychedelic rock posters or op art. They evoke the awestruck, overwhelmed feeling we get when contemplating the vibrating vastness of the universe, but they’re not star maps you could chart your rocket by.

ANGEL: Barbara Takenaga imagines her own worlds rather than getting hung up on the real thing.

In the paintings of Cristi Rinklin of South Boston, plumes of blue and red smoke meander through vast airless theatrical spaces that evoke the flashing, artificially flavored hollowness of the Internet. Much as Ellsworth Kelly finds the geometric shapes for his monochromatic abstractions by isolating the shadows of trees or the stripes of beach cabanas, Rinklin builds her abstract realms by collecting snippets of digital flora and fauna. These are hand-painted works that come out of Photoshop, which she deploys to twist and stretch, blur and layer her source images of Baroque painting, cells, constellations, and natural-history illustration.

Bostonian Julie Miller’s amazing obsessive-compulsive doodle o(1) from 2006 is a giant field of teensy orange circles drawn with needle-pointed pens and topped by weaving lines that lasso bull’s-eye green circles. Pink and yellow paint-marker dots hide camouflaged in the pattern; here and there magenta dots pop out. Miller’s drawings always remind me of microscopic views of circulating blood cells or skin, but a monitor plays her o(15) from 2006, a continuous animation of fields of tiny circles that looks like buzzing TV static.

A case of identity In 2002, the year after his mother died, as Alex Matter tells it, he found a brown paper package in his father’s storage locker on Long Island.

The case of the zombie Pollocks On Monday, Harvard researchers kicked a hornets’ nest that has been buzzing in the art world since the discovery of 32 drippy abstract paintings claimed to be previously unknown works by Jackson Pollock.

Variations and themes The technique of the artist isn’t usually the first thing that comes to mind when you see a work — at least not a successful one.

Selective strife Portland Museum of Art’s “In Our Time: The World as Seen By Magnum Photographers,” is quite literally a catalogue of the most virtuosic photojournalistic photographs in the last half-century.

Neo-rococo Jamaica Plain's Laurel Sparks has become one of our best local abstract painters, as her new collection of bright, fun, juicy, abstracted chandeliers at Howard Yezerski Gallery attests.

Around the edges Focus and framing, two devices that help us zoom in on what we are interested in looking at, and to filter out what we would rather not see, are critical tools not only for artists but for humans in general, as we make our way through a visually complex world.

The thinker at mid century A long time ago (say 70 years), in a galaxy far, far away (New York), a tired band of rebels ached to be the Next Big Thing.

Alternative universe In the 1930s and '40s, Boston painters developed a moody, mythic realism. They mixed social satire with depictions of street scenes, Biblical scenes, and mystical symbolic narratives, all of it darkened by the shadow of the Great Depression and World War II.

The Omelettry Café With a name like the Omelettry, you’d expect an homage to the egg, not the huevo.
